Really, the only categorization issue that I'm adamant about is that Pluto-Charon is called a binary. The Pluto-Charon barycentre is not inside Pluto, therefore Charon is not rotating around Pluto, the two are corotating around a common point of space between them. That's a binary.

The barycenter of the Sun-Jupiter system lies at 1.068 solar radii, outside the Sun. Do you think they should be called a binary?
